'Ihis invention relates generally to shoe machines and more speciiically to an improved maf chineadopted for use in attaching high heels to Womens` shoes with the aidof heel attaching devices of the type covered by United States Letters Patent No. 2,004,979, granted to David E. Cool on June 18, 1935, the` predominant object of the invention being to provide a machine of this type which is intended to perform the same ,w function as the machine covered byUnited States Letters Patent No. 2,144,143, granted to the said David E. Cool on January 17, 1939, but which includes improved details of construction and arrangement.

The heel `attaching device covered by United States Letters Patent No. 2,004,979 referred to above, comprises a hollow element'in the form of a `sleeve which is provided at one end with a flange and at its opposite end with a plurality of displaceable portions, said displaceable portions being provided with inwardly curved faces in Contact with which a Suitable tool is moved to spread the displaceable portions outwardly. In applying the heel attaching device to a shoe `a hole is formed through` the insole of the shoe and in the heel to be attached thereto and the heel attaching device `is introduced into these holes. In its nal heel-securing position in the shoe the iiange of the heel attaching device is countersunk in the insole `of the shoe, and the displaceable portions of the heel attaching device are spread-outwardly so that theyy bite into the material of the heel and in this manner secure the heel to the shoe.

. Theimprovedmachne as disclosed herein includes as an important feature thereof an indexing mechanismwhich carries a plurality of drills and a plurality of punches said indexing mechanism being arranged for rotary movement and straight line movement so that in the operation of the machine the indexing mechanism is rotated to properly position a drill and is then moved in a straight line to perform `the drilling operation, and thereafter the indexingmechanism is rotated to properly position a punch which supports a heel `fastening device and is then moved in a straight line to cause the punch to introduce the heel fastening deviceinto the hole in the insole and heel of the shoe previously formed by a drill andspread the displaceable portions of the heel fastening devices to `secure feeding the heel fastening devices to the punches of the indexing mechanism, and improved means for properly locating with respect to themachine the lasts on which are supported the shoes being operated onby the machine.` All of the features mentioned are4 described in detail in the following `specification and are illustrated in `the drawings in which:

In the drawings.- wherein is shown for the purpose of illustration, merely, one embodiment of the invention I designates the main frame of the machine, said main frame comprising a top plate 2 with which suitable legsf3 are associated; `rThe top plate '2 is preferably, though not necessarily, rectangular in shape when viewed inplan, and if desired plates 4 may be secured tothe legs t `at the four sides of the main frame to enclose the mechanism disposed beneath the tcp plate of the main frame. At the lower portion of the main frame I a vbase plate 5 is secured atits opposite ends `to brackets v6 secured to the legs of the mainframe, saidbase plate serving to support mechanism of the machine which will now be described. y

Supportediby and secured to the base plate \5 lis an electric' motor 1 with which is associated a short shaft@ (Figs. 1 and 5), said shaft being suitably supported for rotation. The motor 'I has associated therewith a gear housing 9 which encloses suitable gearing '(not shown) for transmitting rotary motion frornthe main shaft of the motor 'to the shaft 8.. Fixed to the end of the shaft 8, opposite to thefend thereof at which rthe motor 7 is located, is a clutch element Illas shown to the best advantage in Fig. 5.

Alined longitudinally 'with the-short vshaft i is a longer shaft II which is supported for rotationby a pair 'of spaced bearings It and i3, said bearingsbeing supported byand secured to the base plate 5. ylat-the endof the shaft Il located adjacent to the short shaft 3 said shaft `II has mounted thereon for sliding movement longitw dinally of said shaft a clutch member i4, said clutch member as will presently appear herein being adapted for sliding movement' with `respect to the shaft I I into and `out of clutching engage" ment with the clutchmember lil of the shaft B. The clutch member vlf3 is provided with an annular groove i5 formed therein and associated therewith and preferably forming an integral part thereof is a pinion I5. The structure comprising the clutch `member If@ and the pinion. i6.

is preferablysplined to the shaft I I so that while said vstructure may move longitudinally yof the shaftit rotates at all times with said shaft II. l)interposed between an end face of the bearing I2 and a face of the pinion I5 is a coil spring l? which tends to expand and therebyv move the clutch. member I d into clutching engagement with the clutch member IE! of the shaft 8.

Supported by a bearing i'lextended from 'the bearing I2 and a bearing I9 supported by the` base plate 5 isa shortshaft Eil which has siedlvl mounted thereon a gear wheel 2i which meshes The pinion I5 and gear wheel El are "geared two to one so that the shaft 20 will rotate one complete revou lution while the shaft II is making two complete revolutions. In order to hold the clutch member I out of clutching engagement with respect to the clutch member Ill and to permit the coil spring Il to move said clutch member it into clutching engagement relative to said clutch member Ill during certain phases of the operation "of the machine, a mechanism `is provided which includes a vertical arm 22 which is pivot-V ably secured at its lower end, as shown at in Fig. 1, to an element 2.4i which is pivoted at Erl to a member 2da fixed to the base plate 5. At its upper end the arm 22 is loosely connected to a horizontal arm 25 (Fig. 7) and this arm 25 is loosely'connected at its opposite end to operating `element 26 which is pivoted at 2 to a v bracket 28 which is fixed to the main frame of the machine. p

vThe operating element 2G has associated with it a coil spring 22 which is connected at its oppio site ends to saidoperating element and a bracket 3G vsecured-to ythe Amain frame of the machine. Thefelement '2Q has mountedthereon a rotary roller '3i which extendsv into the annular groove l5 of the clutch member Itas shown in 5. The shaft 2Q has xedly mounted thereon a cam which is provided with a high spot 32 and when the-machine is not operatingthe high spot of thecam v32:' contacts with a side face of the vertical arm l2-as shown in Fig. 5. When, however, itjis desiredto cause the'cl'utch member UI of the shaft II to move'into clutching-engagement with the clutch member I0 of the snai I; 8, the operating element 26 is operated to move the improvedend ofthe vertical arm 22 in the direction indicated by the arrow in Fig. 7. This movement'of the vertical arm 22 will move the portion of said arm with which the high spot of thecam '32 movablvcontacts out of contact with said'high-spot, thereby permitting the coil sp f" "l1 to move theclutch "I into clutching eng ment'with the clutch il?. Itis to be noted that the vertical arm is notched 'to permit it to straddle theshaft 2G when said vertical arm is moved toward said shaft as described. Also the element *24 is provided with a notch through vwhichthe shaftfZ'U extends and this notch of the element 2d is suiciently wide to permit said member 2li to be moved yon its pivot 2t with respectto the shaft l25| when'the clutch member I4 moves toward the clutch member II). The movement of the element 2li mentioned results fromthe fact that the roller 3l thereof is eX- tended into the annular groove l5 of the clutch member I''and thereforemovementof the clutch member I5 in response to force exerted by the coil spring If'I is transmitted to the element Elfi.

Immediately as the vertical arm 2li is drawn .out of contact with the high spot 32 of the cam 32 as described andthe clutch member ifi moves into `engagement with the clutch member if?,

motion is transmitted from the shaft 8 to theV shaft I I. 'AAlso motion is transmitted through the pinion i6 and gear wheel 2i from the shaft Ii to the shaft 2i) whereby the cam 32 is rotated to cause its high spot 32 to move away from the location of the vertical arm 22. Whiie the high spot of the cam 32 is making a complete revolution with the shaft 25] the coil spring 29 associated with the operating element 26 restores the vertical arm 22 to its normal position with respect to the element 2t and as the cam 32 and shaft ZIJ'approach the end of a complete revolution the high spotof the `cam will again contact with the arm Z2 and cam the element 24 rearwardly to disengag'e the clutch member I4 from the clutch member I6 and arrest movement of the shafts Hand 2B. i

Secured to the top plate 2 of the main frame 'l or" the machine at the lower facerof said top plate is a guide 33 which extends downwardly from said top plate and is shaped in cross-section as shown inFig. 4. In other words the guide 33 is provided with an opening 34 formed longitudinally thereof and the portions of the guide atopposite sides of the opening 3d are provided with dove-tail grooves 35 as shown in Fig. d. Supported by the guide 33 for vertical movement with respect thereto is an indexing mechanism 36,-said indexing mechanism including a supporting member 3l which is provided at its opposite sides; with portions 38 (Fig. 4) that are shaped to fit in the dove-tail grooves 35 of the guide 36. The portions 38 are guided for vertical movement by the walls of the grooves 35 `of the guide 33 and because of the dove-tail shape of said grooves lateral displacement of the portions 33 from the grooves is prevented. The supporting member includes also an elongated integral sleeve 35 which extends through the yopening 34 of the guide 33 and beyond said guide. At its i lower end the supporting member 3l is provided with a bifurcated portion 45 between the spaced legs of which the upper end portion of a connecting rod 4i is pivotably connected by ka pin 42, the lower end portion of said connecting rod l being connected to a crank 43 which forms a part of the shaft Il. `In view of the arrangement just described it is obvious that rotation of the shaft Il will impart vertical reciprocatory movement to the supporting member 3l with respect to the guide 33, the sleeve 39 of said supporting member during such reciprocatory movement moving longitudinally of the opening 3d of the guide.

The sleeve 35 of the supporting member 37 receives therein a sleeve 44 which is provided at one end with head 45, said head being provided with a cavity 46 formed therein which is closed by a removable cover plate 4T that is provided with an outwardly extended, screwthreaded shank 45. As will presently appear herein, the sleeve 44 is rotated within the sleeve39 and therefore bushings 45 are provided to facilitate such rotation. By referring to Fig. 2 it will be noted that the head 45 of the indexing mechanism 36 is provided with opposed and alined screw-threaded openings 56, and each of these openings receives the reduced, externally screwthreaded, inner end of a cylindrical housing 5l. Each cylindrical housing is closed at its outer end by a cap 52 which screwthreadedly engages the outer end portion of the associated `housing as .shown in Fig. 2, and each cap is provided with a central opening in which a bushing 53 is arranged.` Supported by each cylindrical housing is a sleeve 54 which is supported for sliding movement within the associated bushing 53 longitudinally thereof,

each sleeve 54 being provided with, a flange 55 at its inner end which is located withinxthe associated cylindrical housing and is of only slightly less diameter than the interior of said cylindrical housing. Arranged within each of said :yli'ndrical housings is a coil spring 56 which contacts at its opposite ends with a wall of the housing and the flange of the associated sleeve 54. iGecause of this arrangement the sleeves are `normally moved to the limit of their outward movement with respect 'tothe housings 5I by the coil springs, such outward limit of movement being lestablished byV the "flanges of the sleeves contacting with vthe inner faces of the caps 52. However the sleeves 54 maybe moved inwardlyrelative to the housings 5l by compressing the coil springs 56.

Extended longitudinally through the central opening of the sleeve `44 of the indexing mechanism 36 is a shaft 5'! which is supported for rotation by a bushing 58 arranged within the sleeve 44 and Within the shank 48 of the cover plate 41 associated with the head 45. The shaft 5l has fixed thereto a bevel gear 59 (Figs. 2 and 4) The bevel gear 59meshes with similar bevel gears 66, each of which is mountedon the inner end of a coupling 6I which is supported forrotation within a bushing 62 associated with one of the cylindrical housings 5I. Each coupling 6| has an opening formed therein which receives, the inner end portion of a-drill 63, the drill being secured to the coupling by a set screw `64. Also each coupling has associated with it a ball bearing structure 65 which facilitates free rotation thereof. `Theouter portions ,of the drills 63 are disposed within the sleeves 54, as shown in Fig. 2, said sleeves being provided'with bushings 66 which support the drills for free rotation within the' sleeves. Additionally each sleeve 54 is provided with openings 61 located adjacent to its outer end through which shavings may pass during` drilling Each of these openings receives the reduced..

screwthreaded inner end portion of a rod 69, each of said rods being provided with a cavity 'ill formed therein, which is closed at the outer end i of the rod by a cap 1l that is screwed on said outer end portion of saidrod. The cap li of each rod 69 is provided with a central opening through which. a sleeve 12 is extended, said sleeves each being provided with a flange 13 which is of only slightly less diameter than the cavity 'l0 of the associated rod 69. Arranged within each of the cavities l is a coil spring` 'i4 which contacts at its opposite ends with the base of the cavity and the `ange ofV the associated sleeve, said coil `springs being adapted normally to `force the sleeves outwardly to the limits of `their vouter movement with respect to the rods 69 where the flanges of said sleeves contact with the associated caps 1l as shown in Fig. 4. Each of the rods 6B.

supports a punch 'l5 which is provided with a reduced, screwthreaded inner end i portion 'l5' that is screwed in a screwthreaded opening formed in the associated rod, the punches being extended from their points of attachment to the rods 69,

through the cavities 16, and through the sleeves j 'l2 to points a slight distance beyond the outer ends of the sleeves and the outer end portions of said punches are `provided taperedfaces 'l5'.

The sleeve 39 of the supportingmember 3l supe ports at an end thereof a block 'i6 to which is xedly attached a bracket 16' (Figs. l and 2). This bracket supports an electric motor 5l which is cooperatively associated with the shaft 51 tact.

upper bearing portion `V8| and the `lower bearing '82 are provided with bushings 83 in which the 8S is xed thereto and this bevel gear meshes with a bevel gear 9!) :which is an integral part of a clutch member 9| that is supported by the reduced portion i of the shaft I I'. The structure providing the bevel gear S0 and the clutch member al is not fixed to the shaft portionv II, but instead said structure is loosely supported on said shaft portion so that during certain phases of the operation of the machine the shaft portion yI I may rotate .with respect to the bevel gear 90 and clutch member 9i.

The shatportion vI i is supported at its outer end yby abearing 92, and mounted on said shaft portion is a clutch member 93, said clutch member being splined to the shaft portion as indicated at 93 `in Fig. 2 so that said clutch member $3 may more longitudinally of the shaft portion into and out of clutching engagement with respect to the clutch member 9|; The clutch memher is provided with a portion 94 which is of greater diameter than the remainder of the clutch member, and 'this larger portion is provided with wina member 99, this member being slidably supported for vvertical movement on a pair of rods Iiii which are xedly supported by the-base 5 or the machine. Each of the rods it?! has mounted thereon a nutI @I and an associated lill', and located vbetween the washers lili and the lower face of the member S9 are coil springs 'H32 which surround said rods. The coii springs it? are under compression sothat they exert upward force against the/member 99 so as to force the strip oi braking material into close contact with'the curved face of the brake element 9i when said curved face of said brake element is in proper position toreceive such conffilso at the upper ends of the rods |90 nuts i533 are mounted thereon to limit upward movement of the member 9S. As shown in Figs. 2 and 5 a coil spring Ili is interposed between the brake element l and the clutch member 33 this `coil vspring tends to move the clutch member Q53 toward the clutch member 9|.

Secured to thesleeve fit of which the head l5 forms a part is a disk |65 (Figs. 1, 2, 3, and 4) which providedwith a plurality of radial slots i. rfhe disk |35 is provided with a central aperture through which the shaft 51 extends loosely so that said shaft and said disk may rotate with r t to each other, and said disk is secured to the sleeve ill by screws It?. As shown to the best advantage in Fig. 3 there are four of the radial slots Iil in the disk |65, and also said disk is'provi-ded with'four notches H38 which are located at the Vperipheral edge of the disk ap- `both of .which are parts ,of theblock V'"5. The

proximately midway of the ends of the slots-.iat said peripheral edge of the disk. Arrangedin association With the disk |05 is a` second disk |09 which is secured by screws |09' to the pinion 18 and this second disk has mounted thereon four boltsV IIB on which rollers lill are mounted. The rollers are so positioned on the disk |09 that as said disk is rotated they will successively pass In order to lock the disk `|95 against uning tended rotation a locking member is provided which is pivoted at its lower end as indicated at H2 to the block 'I6 and is provided with a coil spring Il@ at its upper end. The locking member Ii includes an extension -I I3 which is adapted to enter the notches H58 of the disk |05 when said'disk-has been rotated'to proper positions where said notches mayreceive said extension of the lcckingmember. Also the locking member i EI is provided-With a roller -H into f.

contact with whichlcam faces I I5 formed at the peripheral edge of the disk it move. It is obvious that as rotation of the disk |89 is started the cam face M5 in contact with the roller H4 will cam said roller outwardly against the force of the coil spring I It, thereby movingrthe extension H3 out of the notch illof the disk |05 into which it projected. A curved portion of the peripheral face or the disk IBS), which moves into contact with the roller lill will hold the extension away from the peripheral edge of the disk 585 and during this period the disk It will be rotated ninety degrees by the disk it?! as has been already explained. W'hensuch ninety degrce Vrotation oi the disk l has been comple-ted s another of the cam faces H5 will have moved into position adjacent-to the roller .I iii andalso another notch H38 of the disk lli-5i willfhaveirnoved into position adjacent to the extension |I3 lof the locking member I-iI.

inwardlyby the coil spring H3 into contact with the adjacent cam face I I5 and the extension |-|f3 will move into the adjacent notch It to lock the disk |95.

Each time the machine is stopped after an operation thereoiby the cam separating the clutch members It and Ill as has been previously explained herein, the indexing mechanism comes to rest with the upper portion of one `o1 the sleeves 5ft and the drill therein extended above the top plate 2 of the main frame of the machine'as shown in Fig. '7, sai-d top plate being provided with an aperture 2 through which said sleeve and drill pass. The sleeve so extended above the top plate Eloi the macl'iineserves-.as apost which temporarily supports a last Lion which is arranged a shoe S to be heeled. Lasts, of course, are of different heights and it is necessarytherefore to provide a last supporting means which is adjustable so that the heelseat of .every lasted shoe to be operated on by the machine is the same distance from the top surface of the top plate2 regardless of the height of the last. The adjustable means referred to comprises a lower bar II'I which is provided with a slot HS formed longitudinally therein and open at the forward end of the bar as-shown to the best advantage in Fig. 8, and thelegs IH' at opposite sides of the slot| i8 are provided with inclined cam faces 'Ihe vresult Aof this `situation will be that the vroller will be moved as shown at ||9 in Fig. 1. The forward part of the lower bar ||1 is set down in a cavity |20 formed in the top plate 2 of the machine, the rear portion of said bar resting on the top surface of the top plate 2. t

The last adjusting means includes also an upper member 12| which has a rear portion which is thicker than the forward portion there- -of as shown clearly in Fig. 1, said upper member including also a downwardly extended intermediate portion |22, which is disposed between the spaced legs of the lower bar I and opposed marginal portions |23 which overliefthe legs of the lower bar. The opposed marginal portions |23 of the upper member 12| are provided with inclined lower faces which correspond to the inclined faces at the tops of the legs of the lower bar `H1. The upper member is held in nonsliding position by a bolt |24 which passes through an aperture |25 that is formed through a wall |25 of the upper member that is located at the base of a cavity |21 formed in said upper member. The shank of the bolt |24 extends through the cavity |21 as shown in Fig. 9 and a `coil spring |28 surrounds said bolt shank and contacts at its upper end with the lower face of the head of the bolt and at its lower end with the top face of the wall |26. The coil spring |28 tends to urge the upper member |2| downwardly so as to maintain the inclined faces of the marginal portions |23 of said upper member in lcontact with the inclined faces of the `spaced legs of the lower bar The lower bar ||1 of the last adjusting means has pivoted thereto an arm |29 which is pivoted at one end at I3!) to a shorter arm |3| which is pivoted at |32 to the top plate 2 of the machine. At the opposite endof the arm |29 a connecting element |33 is pivotably attached thereto and this connecting element is attached also to an operating handle |34 which is pivotably attached to a fixed part of the machine at |35 (see Fig. 7)'. In order to retain the operating handle in positions to which it is adjusted a toothed plate |36 is iixed tov the top plate of the machine and teeth formed on the operatinghandle are adapted to engage the teeth of the plate -|36 to lock the operating handle in desired positions.

When a lasted shoe is to be associated with the .machine the last is applied to the sleeve 54 which extends through the aperture 2 of the top plate of the machine, when the machine is at rest,

lthis sleeve passing also throughan aperture `|31 formed through the upper bar I1. At the time a lasted shoe is applied to the machine as described the insole of the shoe is imperforate and the insole will contact the top edge .of the sleeve 54. If the last is of the same height as the preceding last the bottom face of the` inverted last will contact with the top face of the upper member |2| of the last adjusting means so as to support` the last. On the other hand if last being applied to the machine is of less height than the preceding last, the operating handle |34 of the` last adjusting means will be drawn forwardly at yits'upp-er end to slide the lower bar ||1 of the Alast adjusting means with respect to the upper vmember |2| of said last adjusting means and,

through cooperation of the inclined faces of said lower `bar and said uppermember of the last :adjusting means, raise said upper member to cause its top face to contact with the lower face fof the inverted last to support the last. Also if `the `last being applied to the machine is of greater height than the preceding last the lower f bar of the last adjusting means is moved rearwardly to lower the upper member of said last adjusting means to the proper elevation where it will support the last being applied to the machine.

AThe improved machine disclosed herein includes a hold-down mechanism which is `intended to retain a lasted shoe in its proper pol bolted or otherwise secured to the top plate of the. machine, and pivoted to said support at |35 is a pair of spacedarms |40. The forward portions of the spaced arms are supported by a toggle structure which is made up of an upper arm |4| and a lower arm |42, said upper and lowerarms being pivotably connected together at |43, and the upper arm being provided with an'extension |44 which serves as an operating handle for operating the toggle. The lower arm |42 is pivoted at M5 to the spaced arms |411, and the upper arm |41 is pivoted at |45 i between the legs of a bifurcated element |41, said biiurcated element being provided with a screwthreaded .shank |48 which extends through an opening formed through a front extension |33 of the support |38; The screwthreaded shank |43 has nuts |55 mounted thereon which are screwed into contact with the top and bottom faces of the extension |35 `of the support |38, said nuts being adjustable longitudinally of the screwthreaded shank so as to provide `for adjusting the bifurcated element |41 vertically. `The bifurcated element has a bracket |5| secured to it and said bracket has attached thereto at one end'a coil spring |52, the opposite end of the coil spring beingconnected to a bar |53 fixed to the spaced arms |40. `Pivotably attached to the spaced arms |40 by means of a pivot4 pin |54 is a member |55, the portion of said member through which the pivot pin |54 extends being `located between the forward portions ofl said spaced arms |411. vThe member |55 is of substantially inverted L-shaped formation as shown to the best advantage in Fig. 14, including a short substantially horizontal leg 155% and a longer leg |55b which is extended at a substantial right angle relative to said` short leg. The longer leg of the member |55 has a slot |56 formed therein and adjacent to the llower end of said longer leg pins |51 are extended therefrom on vwhich are mounted cylinders |58 formed of felt or other yieldable material. As shown to the best advantage in Fig. 7 the pins |51l and the cylinders |58 are disposed in divergeht relation with respect to eachother.

Associated with the longer leg |55b of the member |55 is a traveling head |59 (Fig. 14) which includes a rear portion |55au that extends into the slot |56 of the longer leg of the member |55, and is provided with shoulders |59b` at opposite sides of said portion |53 which Contact 4with theforward face of the longer `leg of the .screwthreaded opening formed rthrough the short legu|55al of the member |55. y The `lower end por- .-thereof.

tion of the shank of the adjusting screw |60 is connected to the traveling head |58 in such manner that said shank may rotate with respect to the traveling head while vbeing cooperatively connected thereto so that adjustment of the adjusting screw |58 upwardly or downwardly relative to the short leg of the member |55 will impart sliding movement to the traveling head with respect to the longer leg of said member |55. In order to lock the traveling head in positions to which it has been adjusted a bolt |6| is provided. This bolt is extended through the slot |56 in the member |55 and is provided with a head |81a at one end thereof which is large enough to overlap the opposite sides of the slot, said bolt passing also through an aperture formed through the traveling head and being provided with a nut |6|b mounted on its outer, screwthreaded end portion which is adapted to be forced into close, frictional contact with the forward face of the traveling head. It is obvious that the nut ||5|b may be loosened to permit the traveling head to be adjusted after which said nut may be tightened against the forward face of the travelingfhead to lock said head in its adjusted position Also, associated with the traveling head |59 is an element |62 which is pivoted at |58 to said traveling head, said element |62 being provided with a fiat plate portion |62 which is adapted to contact with the top face of an inverted heel when said heel is being applied to a shoe with the aid of the machine disclosed lherein as shown in Fig. 1.

After an inverted lasted shoe has been applied to one of the sleeves 58 extended above the top plate 2 of the machine as previously explained herein,.a heel H is arranged in proper association with the lasted shoe.` Atl this time the toggle provided by the arms |4| and |42 is broken forwardly so that the forward end portions of the spaced arms |48 and the parts associated therewith are elevated above the heel by the coil spring |52. The operator of the machine then grasps the outer endportion of the handle |44 and draws same downwardly whereby through operation of the toggle the forward end portions of the spaced arms hill` are likewise moved downwardly. During such downward movement of the forward end portions of the `spaced arms |48 the heel engaging mechanism `associated therewith is guided by the operator to cause the cylinders |58 to engage the side face of the heel and to bring the flat plate portion |62' of the element |62 into engagement `with the top face of the invertedheel H. After contact has been made with the heel by the cylinders |58 and the element |82 downward movement of the handle IM is continued until the pivot pin |63 moves beyond dead center, at which vtime the forward end portions of the spaced arms |1153 will be locked in their downward position and. thev cylinders |58 and element |62 will hold the heel H iirmly in its proper position with respect to the shoe.

The improved machine disclosed herein includes improved means for feeding heel fastening devices to the punches 15 of the indexing mechanism, This means is shown to the best adyvantage in Figs. 1, 2, 10, 11, 12, and 13 and said ieans includes a bracket |65 which is secured to the top plate 2 of the machine at the lower face The bracket |65 is provided with a downwardly extended plate |652 in which a slot 11651 is formed, the bracket being provided with webs |85c which are alined with the opposite sides of the slot. Pivoted to and between the Webs |65Vb`y means of'a pivot bolt |68 is an arm |61, said arm being provided with a substantial horizontal shank 'portion |t8 at its upper endwhich is externally screwthreaded through a portion of its length The screwthreaded portion of the shankv |68 has a nut mounted thereon and interposed between said nut and the bracket |65 is a coil spring |68, said coil spring being adapted to urge the lower portion of the arm |61 in the direction indicated by the arrow in Fig. 2.

Secured to the arm |61 by suitable fastening devices lla is a member lll which in plan view is shaped as shown in Fig. 15; that is to say said member is provided with a portion |18' which contacts directly with the arm |81, and a portion |1| which is disposed with respect to the portion l'iii as shown in Fig. 15. The portionIll of the member l'l'll is provided with a straight groove |12 formed in its top face andthis groove leads to a semicircular notch |13 that is formed at an end of said portion |1|. Associated with the member |16 is a pair of jaws |14, said jaws being of substantially L-shaped formation as shown in Fig. l5 and being provided with curved cutout portions |15 which when the jaws are in their normal positions cooperate with each other and with the notch |13 of the portion |1| of the member |1i to provide a circular opening. .The

jaws 21d are secured to the portion |11 of the member |18 by bolts |16 which extend loosely through apertures formed through said jaws and are screwed into said portion |1| of said member |18, coil springs |11 being arranged about said bolts and being interposed between the jaws and washers associated with the heads of said bolts. Leading to the groove |12 formed in the portion |11 of the member .|113 is a hollow conductor |18 which communicates with a hopper |19 (Fig. 1), the hopper being adapted to receive heel fastening devices F of the type shown in Fig. 20 and said heel fastening devices being adapted to pass from the hopper through. the hollow conductor with the flanged ends F of the fastening devices trailing the smaller ends thereof. v

Pivoted to the arm |61 by means of a pivot bolt |88 is an element |81 which has formed thereon a pair of opposed wings |82 which are disposed at opposite sides of the arm |61. The element Y| 8| is provided with. spaced extensions |83 between which is supported for rotation a roller |84. The arm |61 has an opening |85 formed therethrough which receives a plunger |81:` that is provided with a pointed end, said plunger being urged toward the element 18| by a coil spring l 81 which is interposed between the inner face of the plunger and the inner face of a screw-threaded plug |88 that is screwed into a screwthreaded portion of the opening |85. The element |81 is shiftable about its pivot IBG to different positions with respect to the arm |61 and said element is provided with depressions |89 into which the pivoted end of the plunger 86 moves to lock said element in the positions to which it is shifted. During operation of the machine disclosed herein the indexing mechanism 36 is reciprocated vertically because of its connection by the connecting rod 4| to the crank 43 of the shaft I. Also the head is rotated while the indexing mechanism is in the lower portion of its stroke by operation of the geneva movement which includes the disks |85 and |69, said head describing an arc of ninety degrees each time it is rotated to successively bring a drill 63 and then a punch 15 to a position where the drill or punch so posiupwardly through the aperture 2', the opposed or` lower punch will likewise move downwardly. It

is during this downward movement of the lower punch that a heel fastening device F is applied to the lower punch, so that when the punchlto which a heel fastening device is applied again reaches the upper position for movement through `the'force of the coil spring |159, in the positionin which said arm is shown in Fig. 2. In this position of the arm a heel fastening device F will be discharged from the lower end of the hollow conductor |18 into the circular opening provided by the notch |13 at an endof the portion 11| of the element and the curved cutaway portions |15- of the jaws |14, the flange F at the upper end of the heel fastening device supporting the device in the circular opening by overlapping portions of the portion |11 of the element 110 and of the jaws |14. In positions adjacent to the locations of the punches the cam |90 is provided with a pair of portions |91 each of which includes a pair of cam faces, one being designated by the reference character |92 and the other by the reference character |93. As the indexing mechanism of the` machine moves upwardly at the top of itsv stroke the roller |84 is `so positioned that it will pass into contact with the cam face |93 at the lower end of the` cam |111!` which will permit the coil spring |69 to swing the lower end of thearm |61 from the position in which it is shown in Fig. 2 to the position said lower end of said arm is shown 'in Fig. 12. In this latter position the circular opening, provided by the notch |13 formed in the portion 11| of the member |10 and thev curved cutaway portions |15 of the jaws |14, is in alinement with the lowermost punch 15. When the indexing mechanism reaches its uppermost position the roller |84 is engaged by a cam face |94, one of which is located adjacent to the cam face |93 of each cam portion 19|, and the element |81 is moved on its pivot |8|1`so as to bring the roller in line with the cam `face |92. As has already been explained herein the element 18| is held in its two different positions by the pointed end of the plunger |36 entering tapered depressions in said element, and when the element |81 is moved by the cam face |94 as described the pointed end of the plunger is forced from one of thek depressions |89 and when the element reaches its other position the pointed end of the `plunger enters the other of said depressions |89.

The element 18| is shifted from a position where the roller is alined with the effective cam face |93 to a position where said roller is alined with the associated cam face |92 at the top of the stroke of the indexing mechanism of the machine and said'indexing mechanism immediately starts to move downwardly. This causes the lower end of the lower punch 15 to move into the heel `fastening device gripped by the jaws 114 and the portion |11 of the member |10. When the lower end of the lower punch 15 has moved into the heel fastening element gripped by the jaws |14 the roller |84 contacts with the high portion of the cam face |92. This causes the arm |S1 to be moved away from the lower punch as shown in Fig. 13 whereby the heel fastening element F is `released from the jaws |14 due to the jaws being spread apart by movement thereof` with respect to the heel fastening device as shown in Fig. 15, the loose attachment of the jaws to the member |10 and the coil springs |11 permitting such spreading of the jaws. 'Ihe arm |61 is moved rearwardly by the cam face |92 until the roller |34 contacts with the i'lat cam face |911 of the cam |911 as shown in Fig. 2, the indexing mechanism continuing its downward movement to the lower end of its stroke. The heel fastening elements F pass through the hollow conductor` |18 with the ilanged ends uppermost and when the arm |61 moves from the position in which it is shown in Fig. 2 to the position of said arm shown in Fig. 12 the lowermost heel fastening device in the hollow conductor is supported by the movingbase of the groove of the portion 11| of the member |111. When the arm |61 is again returned to the position shownin Fig. 2 the lowermost heel fastening element Fin the hollow conductor |18 drops into the circular opening provided by the groove |13 of the member |10 and the cutaway portions 115 of the jaws |14.

In. order to insure free movement of the heel fastening devices into the opening provided by the notch |13 of the member |113 and the cutaway portions |15 of the jaws |14 the cam face |98' is provided with cam projections |95 forme-d thereser on one of which moves into contact with the `15 when said heel fastening devices are applied to said punches as heretofore described herein each punch is provided with an annular groove formed therein in which a split ring 19t formed of spring material is disposed. When a heel fastening device is applied to a punch it is forced over the split ring |96 thereof and the tendency of the split ring to expand against the inside face of the heel fastening device will retain said heel fastening device on the punch.

In the operation of the improved machine disclosed herein the operator thereof applies a lasted shoe to one of the sleeves 54 which is extended through the aperture 2 of the top plate of the machine, one of these sleeves being extended through said aperture 2 each time the machine comes to rest to provide a post that is received in a tube-lined aperture La formed 'through the last L. The last adjusting mechanism of which ythe operating handle |31 forms a part is then adjusted to properly support the last as has been previously explained, and the hold-down mechanism is operated to draw the cylinders 131 and the element -11'12 in contact with a heel which has been previously arranged in proper position relative to the heel seat of the shoe.` After operation of the hold-down mechanism the lasted vshoe with the heel associated therewith is very Yof ninety degrees.

securely held in position `to be `operated on by the machine. The motors 'l and 5l being in operation the operator next. actuates the operating element 26 so Jo cause the clutch members lil and lll to move .into clutching engagement thereby causing themotor 'l to rotate vthe-shafts il and Eil. Rotationl of the shaft il will cause the indexing mechanism of the machine to be moved upwardly because of the connection of said indexing mechanism to the crank of the shaft l! by the connecting rod iii, and upwardly moving rotating drill 53 within the sleeve 54 extended through the aperture 2 in the top piate i will drill a hole through the insole S of the lasted shoe rand into the heel 'I-l as shown in Fig. 16. It is to be noted that when the indexing mechanism moves upwardly to cause the drill :63 lto drill ai hole through the insole of the shoe and in the heel thereof,the associated sleeve 54 is prevented from moving upv/'ar ly because of the contact of the top edge thereof with the'insole of the shoe. Such upward movement of the indexing mechanism with respect to the upper sleeve Ell will cause the coli spring 5t (Fig. 2) associated with said upper sleeve to be compressed.

When the indexing mechanism reaches the upper limit of'its movement the drill will have Vcompleted the drilling operation and the indexing mechanism then starts on its downward movement withdrawing the drill from the hole and eventually withdrawing the `drill and its associated sleeve 54 from the aperture formed through the last L. As the indexing mechanism approaches the lower limit of its downward movement the cam face S4 of the clutch member 93 will move into contact with the roller 95 thereby permitting the coil spring .ill-"t to move said clutch member 93 into clutching engagement with the clutch member 9i. Because of the clutching engagement of the clutch members 9| and Q3 rotary motion will be transmitted from 'the shaft Il through the clutch members Sl, and

'93, bevel gears 89 and S, shaft B, gears 85 and 3d', shaft 80, and bevel gears 'I9 and 'I8 to the disk |055 of a geneva movement, and said disk H19 will transmit rotary movement to the disk 105 of said geneva movement through an arc The rotary movement of the disk |05 will impart like movement to the sleeve 44 of the indexing mechanism because of the fact that said disk H is secured to said sleeve M and such rotation ofthe sleeve i4 will rotate the head 115 through an arc of ninety degrees,

the opposed drills 63, the opposed punches 75, the cam ld and the other parts carried by the head moving ninety degrees therewith.

The rotation of the head E5 being completed while the indexing mechanism is in the lower portion of its stroke, the indexing mechanism moves upwardly with one of the punches posi- -tioned so that it will eventually pass through the aperture 2 of the top plate 2 of the machine, said punch having been so positioned by the previous ninety degree rotation of the head 5. The upper punch which at this time is moving toward the aperture 2 of the top plate 2 has previously had applied thereto one of the heel fastening devices F as has been heretofore explained, and this upper punch moves through the aperture 2 of the top plate 2, through the aperture L' formed through the last L (see Fig. 17) and carries the heel fastening device F supported thereby into the hole drilled through the insole of the shoe and in the heel thereof` as shown in Fig. 18. As the upward movement of the indexing mechanism continues the top edge of the sleeve 72 surrounding the punch l5 forces the flange of the heel fastening element into countersunk relation with respect to the insole S of the shoe on the last L, whereupon upward movement of said sleeve 'l2 will be arrested and continued upward movement of the indexing mechanism will cause the coil spring i4 associated with the sleeve l2 to be compressed. Continued movement of the indexing mechanism after upward movement of the sleeve l2 is arrested will cause the punch l5 to move against the inner faces ofthe displaceable portions Fa of the heel fastening device and said displaceable portions will be forced by the tapered face adjacent to the end of the punch outwardly to cause them to bite into the material of` the heel adjacent to the hole therein as shown in Fig. 19.

VTWhen the displaceable portions of the heel fastening device have been forced outwardly into the material of the heel as described the indexingmechanism has again reached the upper limit of its vertical movement and thereupon said indexing mechanism starts downwardly withdrawing the punch from the heel fastening element in the shoe and eventually withdrawing the punch and its associated sleeve l2 from the aperture formed through the last and from the aperture of the top plate 2. As the indexing mechanism continues its downward movement the lower punch receives a heel fastening device F fromthe mechanism for feeding said heel fastening -devices to said punches as already explained herein, and the indexing mechanism continues its downward movement to the lower portion of its downward stroke where said indexing mechanism is again subjected to a rotation of ninety degrees. The indexing mechanism then moves upwardly withV a drill S3 and an associa-ted sleeve 54 `at the top of the indexing mechanism and in position to be moved through the` aperture 2 of the top* plate 2 and when said sleeve Sil has passed throughsaid aperture 2 and extends above the top `plate 2 ofthe machine the proper distance the high point 32 of the cam 32 will disconnectthe clutch members llly and l0 to stop the machine. It is to be noted that the shaft E l makes two revolutions during a complete operation of` the machine during which a hole is. drilled through theinsole and in the heel of the shoe, the heel fastening element is introduced into the hole so drilled, the displaceable portions of the heel fastening device are spread outwardly v to cause them to bite intol the material of the heel, and the machine is returned to its starting position. During these two revolutions of the shaft H the shaft 2G rotates butV once and when the single rotation of said shaft 2li is completed ment 99 serves to control operation of the shaft il so as to eliminate jerky operation of the machine caused by the weight of the reciprocatory indexing mechanism. To further insure smooth operation of the machine a flexible element i9? is attached to a bracket 191 which is secured to the block` 'it (Fig. l), said flexible element passing over a pulley |98 (Fig. 7) and having a weight 99 suspended therefrom. The weight 19S has a coil `spring 296 attached thereto, said coil spring also being attached to the base plate of the matchine and said Weight and coil spring serving to a shoe associatedv with` the machine and then counterbalance the weight of the indexing mechanism.
